Rate Performance and Spectral Efficiency of Non-Orthogonal Multiple Access for 5G Communication

2019 International journal of recent technology and engineering  
Multiple access is a key procedure which is used from 1G to 4G communication. Different multiple access techniques in different generations create difference in data rate, connectivity, outage performance etc. 5G is the recent technology in which a new multiple access technique must be used to increase the outage performance, massive connectivity and data rate for next generation. This paper gives clear idea about the Non-Orthogonal Multiple Access (NOMA) technique and different challenges to
